Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optical projection method and an optical projection device for a both-purpose projection system and a rear projection television. SOLUTION: The projection system is constituted of a case and a projector unit, and the case is equipped with a display and a plurality of optical devices provided in the case. The projector unit is installed on the back of the case and made convenient for attachment/detachment and movement. When the projector unit projects a video inside the case, the video is projected to the back of the display by the reflection action of the optical device, and when the projector unit is put on the outside of the case, the video is directly projected to the display. Thus, the projection system used both for rear projection and front projection is formed. COPYRIGHT: (C)2006,JPO&NCIPI
